Though BD colors are REALLY simplistic... Yellow, blue, red... No other colors are known though EU cites whole deco variants for environment (red on Geonosis for instance, green, and then the Hasbro decoes sort of filter into the EU)... Of course, Hasbro's got the "basic" BD (cream) decoed in the 3 duty-specific colors too at one point or another to check out for reference as well.
